president obama and secretary hillary clinton there recalled the remarkable influence of nelson mandela and his work to end apartheid in south africa and on the influence it had on the whole world. back in 1994 on the eve of his presidential victory back then, i interviewed nelson mandela for abc's good morning america. i asked him about america's role in stopping apartheid. and i tell you, he was very generous here. let's listen to a piece of that interview. >> what is the appropriate role, generally speaking, of the united states in helping you realize your dreams for south africa? >> as you know, the united states is regarded as the leader of the western world. and the very first head of state welcomed me when i came out of prison and invited me to his country was the president of the united states of america george bush. and pledged the support. president clinton has continued with that policy. he is one of those who listens for carefully to our requests and he responds very positively. the amount that he has located for south africa is a source of great encouragement to us. >> well
